Difference: Projects (16 vs. 17)

TDE host sample paper

• People + contributions: Keck/LRIS spectra (Jean) + any other public data
• Basic idea: star-formation histories, apples-to-apples color/stellar population measurements in background sample, morphological study

Systematic searches for dwarf galaxy TDEs

• Lead: Jean Somalwar (Berkeley/Stanford)
• Other Participating: please let me know if you want to help, would love to have more people involved
• Other Resources: Chandra triggers
• Abstract: real-time search using (1) color-evolution based selection criteria, with minimal timescale cuts, to reject SNe while include anything blue and vaguely TDE-like and (2) a multi-stage dwarf galaxy selection with a CNN to identify z<0.03 dwarfs brighter than ~19.2 from DECam imaging and a separate hostless/faint galaxy component for cases where the CNN isn't reliable. Currently primarily using Lick to classify, but with proposals out for more classification resources. When/if Swift comes online, I will be aggressively triggering.

Archival search for faint/slow transients

• Abstract: this is not necessarily a TDE project, but maybe it will find some weird TDEs. I am running a ZUDS-like pipeline to search for optical transients in stacked ZTF data (currently 6months windows, shifting by 3months). I expect to find lots of AGN, plus maybe some IMBH TDEs if they are indeed slow and faint (and maybe some weird SNe, other unknown transients). The first paper will be on the LSST deep fields (currently running on COSMOS as an initial test), later I hope to do the ZTF+LSST overlap region.
